' To all whom it may concern:

Be it known that I, FRANK A. BRACKETT, a citizen of the United States,and resident of Manchester, in the county of Hillsborough and State ofNew Hampshire, have invented certain new and useful Improvements inSewing and Cementing Machines, of which the following is aspecification.

The present invention relates to a machine for simultaneously settingstitches in and applying adhesive to the work. The particular embodimentof the invention here illustrated is designed for stitching together theparts whichform a composite inner sole,

lacing the stitches in the channel formed 111 one of the parts of suchinner sole, and for simultaneously delivering. cement or other fluidadhesive in the channel, to the end, that, when the seam has beencompleted, the channel flap may be laid over the seam andsecurcd'against the body of the sole without. the necessity of asubsequent cehesive thereto.

menting or pasting operation. In carrying my invention into effect Ihave provided in connection with a sewing machine, which may be anystandard or other-machine, a prcsser foot which is specially constructedso as to provide a part adapted to enter the channel of an inner sole,or other sole, between the body of the sole and the channel flap, whichpresser foot is provided with a channel or passage, or equivalentdelivering means, adapted to deposit adhesive such as cement, paste. oranything suitable for the purpose in the channel. In connection with themachine constructed as above indicated,

I have provided a container for-the adhesive and an improved means forconducting a continuous supply of adhesive in any desired quantity, andat any desired pressure from such container to the delivering point ofthe prcsser foot.

Although I have stated that the particular embodiment of the inventionhere illustrated is applied to a machine .for operating upon innersoles, it is to be understood that I do not limit the invention to thisparticular use alone In the drawings,

Figure 1 is a front elevation of a sewing machine provided witha'presscr foot adapted to serve the purposes of the present inventionand combined with means for supplying adhesive thereto.

Fig. 2 is an elevation as seen from the Fig. l is a plan view of so muchof the parts shown in Fig. 3 as lie below the 4-4 of Fig. 3.

Fig. 5 is a detail sectionon'line 5-5 of Fig. 3.

Fig. 6 is a detail section on line 66 of Fig. 3.

Like reference characters indicate the same parts in all the figures. v

The sewing machine is represented as a whole at 10, and is shown asbeing mounted on a table or other support 11, and as having a base plate12, a needle 18 and a presser foot 1% attached to a vertically movablepresser bar 15. The invention does not necessarily involve anymodification in the structural or operating parts of the sewing machine,exceptof the presser ioot, wherefore the essentials of the invention maybe applied to any sewing machine whether the same is a known or standardtype or is of any other character. Without intending to limit theinvention in any way, I may state line ' that the machine chosen for thepresent illustration of my invention is a standard Singer machine. Suchmachine has the usual feed mechanism, which is concealed by the baseplate 12 and table 11. the usual mechanism tailed description'ot thesame is unnecessary to enable others skilled in the art to construct anduse my invention.

The presser foot is shown in detail in F'gs. 3, 4,.3 and (5. It isconstructed with a shank 16 having an enlarged socket 17 to receivethepresser bar, in which the latter is secured by a set screw 18. Thatpart of the presser foot which engages the work is formed with achannel. or guideway 19 open in its under side and extending in thedirection of feed of the work through the entire extent of the foot, andwith lips in the lip iii, is iei'inecl a pee adapted to admit the penilee g lziteielly ii )ug'ii it illlil open-- he chLnnel er guuiewaiy iili eresser feet cn- Cflbfl' is edepteii in materiel, such.

Upon starting the machine the feeder advances the work andthe driving mechanism reciprocates the needle in the usual or any otherdesired man ner. The passage or nozzle 23 for the adhesive is beyond theneedle in the feeding direction so that the adhesive is not applied tothe work until after the'stitches have been formed. The nozzle portionof the presser foot deposits a strip of adhesive upon the inner surfaceof the channel flap in a position adapted to secure the flap to the bodywhen the flap is turned down after the stitched sole has been taken fromthe ma-- chine. The adjustment of the pressure regu: lating valve and ofthe needle valve above described is made in accordance with the rate offeeding of the work and the character of the adhesive, to cause 'ust somuch adhe sive-to be supplied as will be sufiiciently coat the channelflap withont ex cess'.
